From: <[EMAIL PROTECTED]> Both Outbound and GRUU drafts make use of the instance-ID for different purposes during SIP registration. In GRUU only the instance-ID is needed to generate a GRUU. For Outbound both, instance-ID and reg-ID are needed.
My question now is, whether a GRUU will be generated when a REGISTER is received at the registrar, which indicates both reg-ID and instance-ID in the Contact header. Reading outbound, it seems like instance-ID + reg-ID are *only* used for outbound purposes. I'm not an expert on outbound, but looking at the uses of "GRUU" and "instance" in the outbound draft there doesn't seem to be any intention to forbid GRUU processing. I would assume that GRUU processing and outbound processing are independent, each triggered by the appropriate conditions. The diagram in section 5.4 of draft-ietf-sip-gruu-15.txt suggests that multiple flows for a single UA would share the same GRUU.
